CARPET-RAVELING MACHINE.

SPECIFICATION forming part of Letters Patent No. 456,147, dated July 21,1891.

Application fil September 18, 1890. Serial No. 365,439. (No model.)

To a whom it may concern:

Be it known that I, JOSEPH F. KIESWETTER, of Toledo, in the county ofLucas and State of Ohio, have invented certain new and usefulImprovements in Oarpet-Raveling Machines; and I do hereby declare thatthe following is a full, clear, and exact description of the invention,which will enable others skilled in the art to which it appertains tomake and use the same, reference being had to the accompanying drawings,and tothe figures of reference marked thereon, which form part of thisspecification.

This invention relates to a carpet-raveling machine.

In the industry in which this machine is designed to be usednamely, thatof manufacturing rugs from strips of old or worthless carpet-it has beencustomary heretofore,

after having cut the carpet into strips of de-.

sired width, to ravel out the greater part of the warp by hand, thusleaving the filling or woof to form the pile of the rug. Such procedureis necessarily slow and irksome and presents such diffi'culties that oldcarpet which might be used advantageously for the above purpose isallowed to go to waste, where otherwise it might be employed inbeautifying and adding comfort to a home.

It is the object of the present invention to produce a machine whichwill rapidly ravel or pick away the desired amount of warp from thefilling, thereby leaving the filling in a condition to be manipulated toform the pile. A further object is to produce a machine which shallcombine great simplicity of construction with high efficiency anddurability in use and cheapness of production.

WVith these objects in view the invention consists, broadly, in thecombination of a series of revoluble knives designed-to cut a definitenumber of warp-threads, a series of fingers adapted to ravel or pickaway the severed portions of the warp, and a feed-wheel adapted to movethe strips through the machine.

The invention further consists in the various novel details ofconstruction, as will be hereinafter fully described and claimed.

In the accompanying drawings, forming part of this specification, and inwhich like numerals of reference indicate corresponding parts, l haveillustrated one form of device embodying the essential features of myinvention, although the same may be carried into effect in other wayswithout in the least departing from the spirit thereof, and in thesedrawings- Figure 1 is a perspective view of my improvedraveling-machine. Fig. 2 is a front elevation of the device, showing theknives, fingers, and feed-Wheel. Fig. 3 is a side elevation, partly insection, showing more particularly the feed-wheel. view, the feed-wheelbeing removed, showing the mechanism for operating the ravelers. Fig. 5is a detail perspective of the supporting-frame for the ravelers andknives. Fig. 6 is a perspective detail View of the collar and fingerscarried thereby. Fig. 7 is a similar view of'one of the knives. Fig. 8is a sectional view of a part of one of the collars carrying thefingers, showing the manner of secur-' ing the said fingers therein.Fig. 9 isa detail sectional view of one of the stationary blades of theknives; and Fig. 10 is a detail View of a portion of the feed-wheel,showing the configuration of the periphery of the same.

Referring to the drawings, 1 designates the base of themachine, whichmaybe constructed of any suitable material and of any preferred design.Upon the top of the base is secured the operating-m echanism-supportin gframe2, constructed preferably of metal with the parts integral andformed with parallel bases 3 and 4, vertical standards 5 and 6, andtransverse rods 7 and 8, connecting with and bracing the said standardsand the base 4, which latter carries journal-boxes 10 and 11, arrangedin alignment with similar boxes 8' and 9'oi1 the said standards.

Fig. 4 is a top plan 7 From the base 3 extends anupward curved arm 12,the upper end of which carries a journal-box 13, arranged in alignmentwith the boxes 9 and 11, and in these three boxes is journaled ashaft14, carrying near its forward end a series of collars 15, bearingfingers 16, and the inner ends of said fingers being cleated, as shown,and adapted to enter a threaded socket in the collar, the fingers havingthreaded ends for the purpose of adjustment. A collar 17 is arrangedupon the forward end of the shaft and bearing a knife 18 and at a pointnear the opposite end a gear-wheel 19, which occupies the space betweenthe standard 9 and arm 12,

while the end carries a balance-wheel 20, the object of which is toinsure uniformity of motion to the mechanism. In the boxes 8' and 10 isjournaled a shaft 21, carrying at its for- 5 ward end a series ofcollars bearing the same mechanism as those carried by the shaft lat andperforming the same functions and at the opposite end a gear-wheel 22,designed to mesh with the wheel 19. Arranged to one to side of thesupporting-frame and secured to the base is the standard 23, whichconnects with the base l by means of a bed-piece 24, havingasemicirculargroove formed therein. Each side of the bed-piece the standard is I 5provided with dovetailed grooves 26, in which are mounted movableknife-blades 27, the inner edge of each of which is beveled, as shown at28, so as to form a cutting-edge in conjunction with the knife 18.

Above the raveling mechanism, and mount ed within adjustable boxes 29,is a shaft 30, arranged at right angles to shafts let and 21 andcarrying a feed-wheel 31, arranged be tween the knives andpicker-fingers, the pe- 2 5 riphery of which wheel is serrated ortoothed,

as shown at 32, a portion of which periphery works in a groove 25, abovereferred to. The outer end of the shaft carries a pulley 33, aroundwhich passes a belt 34.- to a pulley 0 on a shaft 36. This shaft alsocarries alarge pulley 37, around which passes a belt 38 to a pulley 39on a shaft 14 for operating the knives and fingers. Boxes 29 areadjusted by means of a screw 46, or they may be made 35 automatic byarranging a spring above the same and beneath the combing-bracket.

As shown in Figs. 6 and '7, the collars 15 and 17 are grooved, as shownat 40 and 41, respectively, to engage a spline on the shaft 40 carryingthe same, so as to admit of the knives and fingers being adjusted, asdesired, and also to facilitate their ready removal, setscrews 42 beingemployed for securing the parts in their adj usted position. The fingers45 16 are also made removable, as shown in Fig. 8, so as to permit oftheir being removed either for the purpose of sharpening or of replacinga new one forone that is broken or worn out.

Having thus fully described the different parts of my device, I willexplain the manner of its operation: The carpet having been cut intostrips of desired widths, the operator inserts the end of one of thesame under the feed-wheel at 44., and its serrations, by engaging withthe carpet, will feed it through the machine, the groove 25 assisting inthis feature by preventing the knives or fingers pulling the same to oneside or another. The feed-wheel is made to revolve very slowly, whilethe knives and fingers travel with high velocity. The knives thus cutthe warp at short intervals and the fingers pick out the severedthreads. As soon as the inner end of the strip passes the fingers itcontacts with a shield 4.5, which guides the finished strip to areceptacle below the mechanism. This shield also prevents the dirt andravelings falling upon the wheels 19 and 22, which would tend to clog orpossibly break them. As stated, the shaft of the feed wheel is mountedin adjustable boxes, the function of which is to allow the wheel toadjust itself or to be adjusted to various thicknesses of carpet. Ifdesired, the fingers may be made adjustable independently of the collarsby means of their threaded ends.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is-

1. In a carpet-raveling machine, the com bination, with a knife arrangedand adapted to sever a definite number of warp-threads, of a series ofpicker-fingers adapted to ravel or pick away the severed portions of thewarp.

2. In a carpet-raveling machine, the combination, with a knife adaptedto sever the warp, of a series of fingers adapted to pick the same, anda feed-wheel arranged at right angles to the knife and picker-fingers.

3. The combination, with the revoluble knives, of the revoluble pickerfingers arranged parallel with the knives and in the rear of the same,and a feed-wheel arranged at right angles to the knives and fingers andbetween the same.

4.. The combination, with the revoluble knives, of the revoluble fingersarranged parallel therewith and upon the same shafts, the stationaryknives arranged at right angles to the revoluble knives and thefeed-wheel arranged parallel with the stationary knives be tween thesame and also between the revoluble knives.

5. The combination, with the revoluble knives, of the revolublepicker-fingers, the stationary knives, the adjustable feed-whee], andthe feed-plate.

In testimony that I claim the foregoing as my own I affix my signaturein presence of two witnesses.
